WPA is a widely used security protocol to protect the wireless communications. Attackers have been working for years to try to crack the WPA password, however there's no known algorithm vulnerability can be exploited in this process. Brute force/Dictionary attack is considered to be the only available attack today to crack the WPA password. In this work, we design and implement the distributed WPA cracking system that can be easily scale and exploit the GPU computation power to greatly accelerate the WPA password cracking process. The system exploits the Amazon EC2 GPU cluster. We believe that due to the efficiency of this attacking system, WPA users are strongly advised to use strong passwords. Countermeasures to this attack remain an open topic.
